[PATCH 5.14 072/432] f2fs: compress: fix to set zstd compress level correctly

[Greg Kroah-Hartman]

From: Chao Yu <chao@xxxxxxxxxx>

[ Upstream commit 01f6afd0f3ccaa2d5f7fb87e7bd910dc17eef06b ]

As 5kft reported in [1]:

set_compress_context() should set compress level into .i_compress_flag
for zstd as well as lz4hc, otherwise, zstd compressor will still use
default zstd compress level during compression, fix it.
